原生视频广告

请选择平台： Android iOS

MediaContent

借助原生广告，您可以访问 MediaContent 对象，该对象用于获取与媒体内容（可以是视频或者图片）相关的信息。该对象也可用于控制视频广告播放和监听播放事件。您可以通过调用 NativeAd.getMediaContent() 来获取 MediaContent 对象。

MediaContent 对象包含视频的宽高比和时长等信息。以下代码段显示了如何获取原生广告的宽高比和时长。

Java

if (nativeAd.getMediaContent() != null) {
  MediaContent mediaContent = nativeAd.getMediaContent();
  float mediaAspectRatio = mediaContent.getAspectRatio();
  if (mediaContent.hasVideoContent()) {
    float duration = mediaContent.getDuration();
  }
}
NativeVideoAdsSnippets.java

Kotlin

nativeAd.mediaContent?.let { mediaContent ->
  val mediaAspectRatio: Float = mediaContent.aspectRatio
  if (mediaContent.hasVideoContent()) {
    val duration: Float = mediaContent.duration
  }
}

视频事件的回调

要处理特定视频事件，请写入用于扩展 VideoLifecycleCallbacks 抽象类的类，并对 VideoController 调用 setVideoLifecycleCallbacks()。然后，仅替换所需的回调。

Java

if (nativeAd.getMediaContent() != null) {
  VideoController videoController = nativeAd.getMediaContent().getVideoController();
  if (videoController != null) {
    videoController.setVideoLifecycleCallbacks(
        new VideoController.VideoLifecycleCallbacks() {
          @Override
          public void onVideoStart() {
            Log.d(TAG, "Video started.");
          }

          @Override
          public void onVideoPlay() {
            Log.d(TAG, "Video played.");
          }

          @Override
          public void onVideoPause() {
            Log.d(TAG, "Video paused.");
          }

          @Override
          public void onVideoEnd() {
            Log.d(TAG, "Video ended.");
          }

          @Override
          public void onVideoMute(boolean isMuted) {
            Log.d(TAG, "Video isMuted: " + isMuted + ".");
          }
        });
  }
}
NativeVideoAdsSnippets.java

Kotlin

val videoLifecycleCallbacks =
  object : VideoController.VideoLifecycleCallbacks() {
    override fun onVideoStart() {
      Log.d(TAG, "Video started.")
    }

    override fun onVideoPlay() {
      Log.d(TAG, "Video played.")
    }

    override fun onVideoPause() {
      Log.d(TAG, "Video paused.")
    }

    override fun onVideoEnd() {
      Log.d(TAG, "Video ended.")
    }

    override fun onVideoMute(isMuted: Boolean) {
      Log.d(TAG, "Video isMuted: $isMuted.")
    }
  }
nativeAd.mediaContent?.videoController?.videoLifecycleCallbacks = videoLifecycleCallbacks
